OIL BURNER.

To It ac/10m it may concern:

Be it known that LA THUR H; BRAINERD, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Oil Burners, of which the following'is a specification.

This invention relates in general to petroleum oil burners, and it has particular reference to the construction of novel means for diffusing and gasifying the oil.

It is well known that, in hydro-carbon burners the intensity of the heat produced is governed by the degree of combustion of the fuel element employed. It is also well known to those familiar with burners of this class, that a blue flame indicates perfection of combustion and therefore the maximum of heat produced. Withthe use of petroleum as a heating medium, it has been found, that to obtain the blue flame it is essential that the oil be completely gasified before it enters the mixing and combustion chamber.

The primary object of the present invention is the provision of simple, inexpensive, and eificient means for reducing the oil to a gaseous state and delivering it in that con dition to the burner. With this object in view, the invention consists principally in the novel construction of a difiusing and heating chamber, and its relative arrangement with the burner, as hereinafter fu ly described and pointed out definitely in the appended claims, reference being had to the accompanying drawings which are made part of the specification, and wherein similar reference characters are employed to designate corresponding part-s.

ln the said drawings Figure 1 illustrates one form of the improved burner as em bodied in a domestic radiator. a portion of the radiator casing being broken away.

Fig. 2 is a. fragmentary view of the said burner in longitudinal central section.

Fig. 3 is a section on line 8 3 of Fig. 2.

Fig. lis a fragmentary sectional view of the end of the burner opposite to that shown in Fig. 2.

Fig. 5 is a fragmentary view of the generating member. e

I am aware that it is not broadly new in the art to employ a burner, member and a connecting generating member, and I realize that in order to make clear the full meaning of my improvement it will be necessary for Specification of Letters Patent. i Patented M -App1ication filed October 9,1820. Serial No. 415,896.

inc

to differentiate my present invention from others of the same class which may appear at first to contain substantially the same elements.

Referring now to Figs. 1 to 5 inclusive, an embodiment of my invention comprises a burner member 1, a generating or gasifying member 2, and a connecting member 3 provided with a'needle-valve 4:, the member 2 being connected through the valve 5 with a supply source 6 which communicates with a suitable tank not shown.

My invention lies principally in the construction of the generating member, whereby the petroleum is completely gasified before it enters the combustion chamber.

The member 2 is connected at one end with the supply pipe 6 through the valve 5, and extends parallel with and above the burner member 1, the opposite end 2 being connected with the fixture 3. Said fixture 3 is attached to the member 1 at the open end, as shown at 3. The member 1 provides a mixing chamber 1" closed at one end as shown at l and has a series of slots 1 formed therein, said slots opening into the chamber 1". A needle-valve 4 controls the supply of fuel flowing from the generating chamber to the combustion chamber.

The member 2 is preferably made of seamless tubing, which is adaptable to transformation without damage. The end portions of said member are retained circular in cross-section for a certain distance, as shown at 2 and 2 Intermediate the portions 2" l and 2" the member is flattened in alternate sections at right angles to each other laterally, as indicated at 2 and 2 This formation provides a variable bore in the member between the parts 2 and 2, which retards the flow and increasesfthe disintegration of'the oil, the irregularity of the walls acting as baflies. After the initial generation of the gas, by auxiliary means, the generation is kept up by the heat from the orifices 1-in conjunction with the auxiliary means.

The primary or auxiliary heater, in this embodiment, comprises an electric coil 7 superimposed on the element 2 and connected with an electric source, not shown.

The operation of the burner, in general,

is similar to that of burners of this class heretofore in common use, but the modifications provided by the novel construction of the gasifying members and the priming for said chamber, a burner member'located beneath the generating element, and needle valve connection between said generating element and the burner.

2. In a petroleum burner, the combination with an oil supply source, of a gas generating member connected with said supply source, said generatmgelement being flattened in contiguous sections alternately disposed at rlght angles to each other, an electric heating c011 surround ng said member,

a burner member located beneath the generating element, and needle-valve connection between said generating element and the burner.

3. In an oil burner, a gas generating element comprising a tubular member having flattened surfaces arranged in alternate continuous sections flattened at right angles to each other laterally, and provided with an electric heating coil which surrounds said flattened tubular member.

l. In'an oil burner, a gas generating element comprising a tubular member flattened in contiguous sections alternately disposed at right angles to eachother.

In testimony whereof I afiix my signature.
